Title: A system and method for determining the tone of a syllable of mandarin chinese speech
Inventor: HON HSIAO-WUEN
IPC: G10L25/90
Filed: 1995-09-29
Abstract: A tone recognition system for Mandarin Chinese speech recognition comprises an A/D converter, segmenter, coefficient determinator, coefficient modeler, and comparator. The A/D converter is for digitizing an input signal that includes a syllable of Mandarin Chinese speech. The segmenter parses the digitized input to isolate the syllable. The coefficient determinator estimates the pitch of the syllable and determines a second order polynomial that best describes the pitch and determines the duration of the syllable. The coefficient determinator provides the polynomial and duration to the comparator. The coefficient modeler provides models of the tones of the tonal language to the comparator. A model comprises an expected second order polynomial and expected duration, with a co-variance matrix, that describes the language tone. The comparator compares the polynomial and duration to the models using a multivariate normal density, selects the model that best matches the polynomial and duration, and generates a output indicating the selected model.

Title: Personal sun visors
Inventor: SPENCER ALAN
IPC: G02C7/10
Filed: 1998-01-02
Abstract: Personal sun visors are designed to protect the pupils of the eyes from direct sunlight when the sun is at a low elevation. The visors are attached to a supporting frame, or can be incorporated as an integral part of a frame, in such a manner as to be held at a constant height, relative to the head. Part 16 may be mounted in a frame and may slide in it (Figs 5, 6). In normal wear, the bottom edge of the visors should be above the normal horizontal line of sight, leaving clear vision below the visors. In order to bring the visors into effect, the wearer need only incline their head slightly in order to position the visors between the sun and the pupils of the eyes to achieve the desired shade.

IPC: B29C35/08
Filed: 1998-06-05
Abstract: A method of manufacturing an optical disc master includes preparing the surface of a glass master plate (2) with an adhesion promoter 4. A photoresist layer (6) is coated on the adhesion promoter (4). This photoresist layer (6) is subjected to a first exposure of a modulated laser beam (8) to produce an exposed photoresist layer (10) corresponding to the modulation information of the laser beam (8). A transparent sheet (16) is placed on the photoresist layer (6). This sheet (16) contains a distinguishing mark to be located in the optical disc. White light (18) from a second light source is passed through the sheet (16) onto the photoresist layer (6) to expose the upper surface of this layer (6). The exposed part of this upper surface provides a pattern (22) corresponding to the mark on the sheet (16). The exposed master plate (2) is then developed to form the pits (12) and a reproduction (24) of the pattern (22).

IPC: F16J15/12
Filed: 1998-08-14
Abstract: A gasket for sealing the annular space between two concentric pipes comprising an annular elastomeric member (10) and compression members (20, 22).

The elastomeric member and the two compression members have complementary profiles, end faces (16, 18) of the elastomeric member are concave to engage the internal convex faces of the compression members. The elastomeric member may include a void on the radial edges (see fig. 2) which can contain an additional filler ring (32, 34, fig. 4) to engage the pipe surfaces instead of the elastomeric member. The elastomeric member may also be formed in two or more parts (see fig. 3). The compression members can be unitary or may be divided into a series of arcuate portions around the annulus with upper and lower arcuate portions staggered.

Title: Waste energy recovery in amplifiers
Inventor: DENT PAUL W
IPC: H03F1/32
Filed: 1995-01-11
Abstract: Various amplifier arrangements are described including: deriving constant amplitude signals from varying amplitude signals (amplitude information contained in phases) for application to non-linear amplifiers to increase efficiency and the use of a matrix of amplifiers responding to a plurality of inputs to increase the flexibility of use and the disposal (eg by radiation into a harmless direction) energy of intermodulation products. This application is concerned with the recovery of the energy in unwanted signals such as a difference signal or intermodulation products. Figure 18 shows an arrangement with a cascade of diode rectifiers coupled so that any reflected energy is not returned to the source but goes to any following stage. Each stage is arranged to operate efficiently at the incident power level to maximize recovery. Figure 19 discloses a distributed version.
